RULESET-OF
==========
syntax: (ruleset-of <rule-specifier>
[:IDENTIFIER T | NIL | Var]
[:KB <kb>])
Warning: Two rules with the same names can exist in
different sets! Hence first hit. Here the
emulation can refuse, because B3 works here
with instances!
The key :KB is unsupported yet!
This function returns the set of rules, which contains
the given rule. If you set ':IDENTIFIER' to T, then
you get back the name of the set of rules. If you set
':IDENTIFIER' to NIL, then the set of rules will be
returned as an object.
example: >(ruleset-of '(holidayoffer holidayselection)
:identifier T)
HOLIDAYOFFER
